I want to know How to send HTML enabled mail through PHP's mail() function as if i would try this to send HTML by putting it in mail() function it would certainly give error as it may contain other symbols like
so PHP would try to interpret in its own way so how I can assign it to variable and then put the name of variable in mail() function like
But here is the problem as when i would assign value in which way i can assign
because it had quotes ...Any help??

Code:
<>;" etc
PHP:
$myvar="<h1><font color="red">Good </font></h1>";
mail("to@someone","subject",$myvar,"header");
Code:
<font color="red">
